WARNING! When removing any fuel

the opening to catch the fuel. NEVER
use a shop rag to catch the fuel. Vapors
from the rag are flammable and
explosive. Wipe up any spills
immediately. Wear eye protection. The

hours or one year of operation.

tighten the center bolt (Figure 1, (1)).
4. Check for fuel leaks. WARNING! Avoid
skin contact with the high-pressure
diesel fuel spray caused by a fuel
system leak, such as a broken fuel
injection line. High-pressure fuel can
penetrate your skin and result in
serious injury. If you are exposed to
high-pressure fuel spray, obtain
prompt medical treatment. NEVER
check for a fuel leak with your hands.
ALWAYS use a piece of wood or
cardboard. Have your authorized
Yanmar Marine dealer or distributor
